Step-by-step explanation:
add 77+33=108
all triangles equal 180, so subtract 180-108=72
PLEASE HELP IM TIMES AND EXPLAIN STEP BY STEP , so using substitution method solve the system of equations , y = 2x + 8 and y = 4x - 2 , whoever answers step by step gets brainliest
Answer:
y= 2x + 8 , y = 4x - 2
2x + 8 = 4x - 2
8 = 2x - 2
10 = 2x
5 = x
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
y = 2x + 8
substitute the y in the other expression with this expression (you can do it vise versa too but i chose this because it was first)
2x + 8 = 4x - 2
goal is to isolate the variable
add 2 to both sides (this cancels out the -2 on the right side)
2x + 8 + 2 = 4x - 2 + 2
2x + 10 = 4x + 0
2x + 10 = 4x
subtract -2x from both sides (cancels out the 2x on the left side)
2x - 2x + 10 = 4x - 2x
0x + 10 = 2x
10 = 2x
divide both sides by 2 (cancels out the 2 on the right side)
10 ÷ 2 = 2x ÷ 2
5 = 1x
5 = x
variable is isolated and tells us that x = 5

Speedy Swift is a package delivery service that serves the greater Atlanta, Georgia, metropolitan area. To maintain customer loyalty, one of Speedy Swift's performance objectives is on-time delivery. To monitor its performance, each delivery is measured on the following scale: early (package delivered before the promised time), on-time (package delivered within 15 minutes of the promised time), late (package delivered more than 15 minutes past the promised time), or lost (package never delivered). Speedy Swift's objective is to deliver 99% of all packages either early or on-time. Speedy collected the following data for last month's performance:

In the state of New Mexico, 85% of the land is above 4,000 feet in elevation.
Which fraction is equivalent to 85%?
A 4
5
B
100
17
20
1
85
Answer: 17/20
==============================
Work Shown:
x% = x/100
85% = 85/100
85% = (17*5)/(20*5)
85% = 17/20
------------
You could also go through all the answer choices to see what works and what doesn't.
For instance, 4/5 = 0.80 = 80%, so that is a non-answer.
But 17/20 = 0.85 = 85% which is the answer.
Chandler is three more than 5 times as many years old as his sister Kayla
In 9 years he will be twice as old as she will be then, How old is Chandler
now?
A.2
B.11
C.13
D.15
E.22
Answer:
Chandler is C 13 years old
Step-by-step explanation:
5x2=10
10+3=13
Makeing the answer C
Now Chandler's age will be 22 now. Then the correct option is E.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chandler is three more than 5 times as many years old as his sister Kayla. In 9 years he will be twice as old as she will be.
Then the equation will be
C = 3 + 5K ...1
C + 9 = 2(K + 9) ...2
From equations 1 and 2, we have
3 + 5K + 9 = 2(K + 9)
5K - 2K = 18 - 12
K = 2
The Chandler's age will be
C = 3 + 5K
C = 3 + 5 x 2
C = 13
Now Chandler's age will be 22 now. Then the correct option is E.
